Hello.
I can't find the oil specified in my service book. The name of it is Castrol Differential BOT 720, and i need it for my rear diff. electronic unit.
The problem is that i cannot find it anywhere. What would be a replacement of it or where could i find it ?!

 

Dealer only probably -

see L322 02 transfercase oil, What oil to use? - Australian Land Rover Owners

 

I found the Castrol Syntrax Long Life 75w-90 fully synthetic. Is this product good enough for for my rear diff electronic unit?

Thank you!

 

It is a good product, but it is not the exact same as what is in the tech manual which is made by them for one customer - Land Rover. If it was the same, Castrol would sell it to everyone.

Save money with Castrol Syntrax Long Life 75w-90 fully synthetic, perfect for non-locking front and rear differential. I used a little over two quarts for my front and rear. All synthetic gear oil is good as well per dealer. Locking rear differential oil may be a dealer item only. I have 06 RRS SC.

 

BG differential fluid. its cheaper and works the same. We use it on all the diffs on land rovers.
